Subject: [PATCH 211/290] genirq: update irq_set_irqchip_state documentation
|
|
|
|
|
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=8b11399a6330d802b28290410bb88dd784a962e2

|
|
|
|
|
On -rt kernels, the use of migrate_disable()/migrate_enable() is
|
|
|
|
|
sufficient to guarantee a task isn't moved to another CPU. Update the
|
|
|
|
|
irq_set_irqchip_state() documentation to reflect this.
